Grade 4, Module 7: Exploring Measurement with Multiplication
What is this module about? In this final module, students build their competencies in
measurement as they relate multiplication to the conversion of measurement units. Students
explore multiple strategies for solving measurement problems involving unit conversion.
What came before this module? Students explored decimal numbers and their
relationship to decimal fractions. They learned to express a given quantity in both fraction
and decimal forms and compared decimal numbers using the place value chart.
What comes after this module? This is the final module of Grade 4.

like ounces and pounds.
Review time by asking
questions, such as, “How
many more minutes until the
next hour? How many hours
until the next day?”

smaller unit.
Two-Column Table
Spotlight on
Math Tools
Module 7 focuses on customary measurement units (gallons, pints, yards, etc.).
Students decompose them, convert them, and strengthen their sense of what
each customary unit represents. Two-column tables are an important
organizational tool that helps students see how the larger and smaller units
relate to each other, as well as what a “unit” means in each situation, e.g., 16
ounces = 1 pound. Two-column tables also reappear as organizational tools in
later years, such as when students learn simple linear functions and use the
tables to calculate coordinate pairs. In this module, the structure of the table is
provided for students in order to scaffold their learning, to record the
conversion from larger to smaller units, and to see the multiplicative
relationship between two units of measurement.

measurements from Module 7
Sample problem from Module 7 (Lesson 10):
One pumpkin weighs 7 pounds 12 ounces. A second pumpkin weighs 10 pounds 4 ounces. A third
pumpkin weighs 2 pounds 9 ounces more than the second pumpkin. What is the total weight of the
three pumpkins?
